Backup: MML create a backup piece

Hello all,
I thought i should post an RMAN question at the right place, so pointing this question to the one i asked couple of days back in right place....
Backup: MML create a backup piece

i totally agree on not backing up to tape...but we have our limitations($$$$) and other thing....So for that reason we have to go to tape...and hence the issue of that wait...
any idea about that wait?? i mean is it making my DB/server slow because its waiting for "Backup: MML create a backup piece"....like i mentioned on OEM...i do not see that wait on the performance page...its only when i go to the TOP ACTIVITY page i see taht wait...

Please copy the backup pieces and archivelogs from the target database to the standby database..Do remember that the location on the standby database node must be same as of the target database node..
For example : if the bkp pieces of target db node is on '/ora_backup/target_name/bkp' then the same locaiton must be created on standby
if the archivelogs of target db node is on '/ora_backup/target_name/arch' then the same location must be created on standby
Hope its clear.

Catalog Backup Piece Manually

We are currently running Oracle 10.2.0.4 and IBM TSM to do our backups, but we moved to a new machine and some of our older backups are sitting on tape in TSM and i need to manually catalog these pieces, I logged a SR with Oracle and they sent me the following response
+"There is an undocumented command that allows catalog backuppiece from tape,+
+catalog device type 'SBT_TAPE' backuppiece '<name>';+
+You need first configure an sbt_tape device and then you can execute the catalog device type sbt_tape+
+command.+
+As and example the following will catalog a backuppiece on netbackup:+
+CONFIGURE CHANNEL DEVICE TYPE 'SBT_TAPE'+
+PARMS 'ENV=(NB_ORA_CLASS=sv2n2admoraclelogbkup, SBT_LIBRARY=/usr/openv/netbackup/bin/libobk.sl64';+
+catalog device type 'SBT_TAPE' backuppiece 'orig-lij1qaa3_1_1';+
+Note: This command works from 10g. The reason why it is not documented for tape is if the backupset contains more than one piece, then it will take long time to catalog backup piece. As long as there is one backuppiece per backupset, then the undocumented way should work without any issues."+
This solution is for netbackup when i try the following in TSM
RMAN> CONFIGURE CHANNEL DEVICE TYPE 'sbt_tape' parms
'ENV=(TDPO_OPTFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.opt)';
RMAN> CATALOG DEVICE TYPE 'SBT_TAPE' BACKUPPIECE 'tiaprd_monthly_rman_7pl75al9_3_1';

Hi Grant,
As you can see it fails but if i specify a wildcard "tiaprd_monthly_rman*" it works anybody please help.It isn´t an undocumented feature without a reason.
Why not just use the wild card option anyway saves you a lot of time keying in unique tag names?

RMAN-20260 error while trying to delete a backup piece

Hello,
In my company we use Oracle 10g, backup managed by RMAN and integrated with TSM.
In order to remove the old backup files, there is a delete script to do this.
Basically this script:
connect to RMAN catalog
allocate channel for maintenance device type 'sbt_tape'
change backuppiece <file names from rc_backup_piece older than 35 days> delete;
When this command is run, this error is being generated:
RMAN-03002: failure of delete command at 01/18/2010 17:14:00
RMAN-06004: ORACLE error from recovery catalog database: RMAN-20260: backup piece not found in the recovery catalog
RMAN-06092: error while looking up backup piece
Any ideas?
Thanks in advance.
Fer

Hy Tycho,
Yes, it's a tape backup.
This is the channel used to take the backup:
allocate channel t1 type 'sbt_tape' parms 'ENV=(TDPO_OPTFILE=/opt/tsm..../...opt)';
I tried this rman command with a file name that is 35 days older in rc_backup_piece:
list backuppiece <file name>;
I received this error:
RMAN-20260: backup piece not found in the recovery catalog;
How can this file be in the rc_backup_piece and not appear in the list backuppiece ?
Thanks a lot.

Restore backup pieces from tape to disk

Hello,
I want to restore the backup pieces from tape to disk. Is there any way of getting those bacup pieces to disk.
I have contacted storage team, that they can't copy the files, only through rman utility the files can be used.
I just need to restore the files from tape to disk. No, need to restore the database. I just need this for future purpose...
Thanks,
Ramesh G

You can try to use LIST BACKUP to get the backup piece name and then use Veritas tool to restore the backup piece from tape to disk.

I have catalog the backpeince and resync the database and triggered the backup again,but still the same issue
Can anyone throw some light
Regards,

I believe that RMAN literally cannot either 1) find the file or 2) access the file due to permissions on the backup file piece or the RMAN directory above it.
Cheers!

Will RMAN remove invalid backup pieces from Backup tests?

DB Version: 10.2.0.4.0
Thinking that Level1 backups don't take much time, In production, I was testing a Level 1 bkp (I took a level 0 bkp of our 700gb only yesterday).
But, the end users were complaining that system has become very slow. So, i've cancelled the LEVEL 1 backup.
Now i can see 5 backup pieces wasting some space.
I know that RMAN removes expired backup like
delete expired backup;But, how do i script RMAN to remove files mentioned above ie.files from a backup that was aborted halfway through ?

Hi Insignificant
But, how do i script RMAN to remove files mentioned above ie.files from a backup that was aborted halfway through ?If you can locate them on the OS level you could remove them with OS commands.
For backup pieces containg datafiles use <crosscheck backup;> followed by <delete expired backup;> with rman client.

Restore backup piece from tape to disk?

Hi,
Is it possible to restore rman backup piece from tape to disk? Please advice.
Thanks,

Is it possible to restore rman backup piece from tape to disk? Please advice.I dont think so it is related with ORACLE database to copy backup pieces from tape to disk.
You might have any other vendors like veritas, Symmetrix & all. We backup an Oracle database via the TDP application to tape

RMAN ORA-19870: error reading backup piece 'location'

Hi All ,
I have run a restore from a RMAN backup and i got this error :
ORA-19870: error reading backup piece XX_df_23_11_2011_XXX_1_1.rman
ORA-19599: block number 616206 is corrupt in backup piece XX_df_23_11_2011_XXX_1_1.rmanThough the RMAN backup is still going on , it has not errored out, How can i find what all gets missing from the Source database , as in what all is present in the missing block ?
What is the use of MAXCORRUPT parameter ? can that be used here ? can this be prevented if i use maxcorrupt =1 and then run the restore ?
Also , Is there any way in which i can verify that all the backups are perfect before i drop my earlier database and run the restore. I think its the validate command but I am not sure, hence seek expert suggestion.
Please suggest
Thanks
Kk

RMAN backup Fails with ORA-19599,ORA-19600 and ORA-19601 [ID 779386.1]

What is RMAN backup piece ?

Hi,
Kindly explain me in simple terms what is rman "backup piece". Document is saying "The physical file format used to store RMAN backup sets.". What do you mean physical file format ? Little confused with this terminology.
thanks & regards
pjp

You can make an analogy with tablespaces, where one tablespace must have at least one datafile, but can have one more than.
As:
Tablespace = backup set
Datafile = backup piece

Restoring Backup piece on tape from FRA without RCAT using ASM

DB: 10.2.0.3
ASM: 10.2.0.3
Nightly, I have a job that backups the FRA of a 10203 DB to tape using RMAN. The FRA is on 10203 ASM. The tape is loaded, and the channel is allocated. What i'm trying to do is re-catalog the backup piece to the non default location (Disk). IE - I want to get the backup off of tape (I can only use RMAN to do this) and back onto disk and use it for Restore and Recovery...I thought it would be something as simple as specifying a non default location to restore it to but that's not working. I wonder if I have to change the db_recovery_file_dest first and then try it....any one try this before? thanks.

You should be able to restore from tape to ASM then perform the following:
RMAN> backup backupset <backupset_key> format '<disk_directory_path/format>';

Identify L1 backup pieces and restore the latest control file

DB version:11.2
Platform : Solaris 11
We dropped a Development DB last month. But we kept the Level0 and Level1 rman backups plus the archive logs generated after the last L1 .
Our L0 and L1's were scheduled with a 4 day gap.
Now the dev team wants this DB to be restored in a different machine. We hadn't stored rman metadata in a catalog schema. All we have is the below backup pieces.
stcdev_p4lor85q_1_1.bkp
stcdev_yls3gkjl_3_7.bkp
stcdev_mhfr8293_5_4.bkp
stcdev_ipxsr8293_5_4.bkp
.I don't know which of the backup pieces are from L1 and which ones are from L0. If I manage to restore the latest control file from the latest L1 backup , then things will be easy. What if I mistakenly restore the old control file from L0 which doesn't have any info on any new datafiles/tempfiles I've added after that L0.
What would you guys do for situation like this?

After you restore the controlfile, simply ALTER DATABASE MOUNT and then issue a LIST BACKUP. That listing will show you what the controlfile is aware of --- if it shows both L0 and L1 backups, you can use it. If it shows only the L0 backup, try restoring the "other" controlfile.
If you can see the timestamps of the backuppieces, that would help you identify which is the "later" backup.

RMAN backup piece corruption.

Hi,
I m having multiple databases where RMAN backup configured and scheduled. I want to know from backup piece how I can know the block corruption?

What is the version of your RMAN utility.
Try this:
Start RMAN and connect to a target database and recovery catalog (if used).
Run the BACKUP VALIDATE command.
For example, you can validate that all database files and archived logs can be backed up by running a command as shown in the following example. This command checks for physical corruptions only.
BACKUP VALIDATE
DATABASE
ARCHIVELOG ALL;
To check for logical corruptions in addition to physical corruptions, run the following variation of the preceding command:
BACKUP VALIDATE
CHECK LOGICAL
DATABASE
ARCHIVELOG ALL;
In the preceding examples, the RMAN client displays the same output that it would if it were really backing up the files. If RMAN cannot back up one or more of the files, then it issues an error message. For example, RMAN may show output similar to the following:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
